摘　　要：利用激光剥蚀等离子体质谱测定甘肃礼县、陕西陇县、宝鸡、凤翔出土的春秋时期秦青铜器中微量元素.研究发现:青铜器物不同组成部分所用原料是相同的,同一器物本体和补块使用了同样的原料.因子分析显示礼县、陇县、宝鸡和凤翔四个地区秦青铜器中的微量元素组成无显著差异,说明秦人可能已经拥有独立的矿冶和青铜制造业,而且有着比较稳定的矿料来源.激光剥蚀等离子体质谱具有的特点,为测试青铜器残存基体中的微量元素提供了非常好的测试研究方法.研究结果进一步丰富了春秋时期秦人历史文化研究的内容,也为研究文物微区的微量元素组成提供了新方法.The trace elements in bronzes were collected from Lixian museum and Longxian museum in Gansu, Baoji museum and Fengxiang museum in Shaanxi were tested and analyzed by laser ablation inductively coupled plasma mass spectrometry. It was found that same material was used in different parts of the same bronze and bronze body and its supplements were also made of the same material. Based on the factor analysis no obviousdifference in trace elements was found in bronzes between the four areas and this result might imply that ancient Qin people possessed independent mining and bronze manufacture skills and stable mineral resources. In addition, the character of laser ablation inductively coupled plasma mass spectrometry was a suitable method for trace elements analysis in the remaining body of bronzes. The results have enriched the Qin cultural research. Besides, the study also provides a new method for microanalysis of the trace elements in ancient artifacts.
